What are the Main Risk Factors Associated with Erectile Dysfunction in the Elderly? A Cross-Sectional Study of 2436 Brazilian Elderly Men.

Background: Erectile dysfunction (ED) is a multifactorial medical disorder often neglected in clinical practice between elderly men, defined as the inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual intercourse and a common clinical entity among men and associated with impaired quality of life and cardiovascular diseases in elderly men. The aim of this study is to evaluate the association between ED and clinical, demographic and behavioral parameters in elderly men. Methods: A total of 2436 males aged 60 years and over who participated in the health screening between January 2008 and December 2018 were included in this study. Laboratory exams, clinical and behavior profiles were analyzed. Logistic regression models were used. Results: Men with ED were older (65.87±5.49 vs. 63.85±4.05 years old. p<0.001), higher prevalence of physical inactivity (23.8 vs. 19%, p = 0.039) and had a higher body mass index (BMI; 28.36±4.06 vs. 27.72±3.89 kg/m2. p<0.001) than men without ED. The multivariate model shown that hypertension (p = 0.001), diabetes mellitus (p<0.001), lower urinary tract symptoms (LUTS), depressive symptoms (p<0.001) and age (p<0.001), were strongly associated with ED. Conclusion: The main risk factors associated with ED in elderly men were hypertension, diabetes mellitus, LUTS, depressive symptoms and age.

The association between physical activity and erectile dysfunction: A cross-sectional study in 20,789 Brazilian men.

INTRODUCTION: Erectile dysfunction, defined as the inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual intercourse is associated with impaired quality of life and cardiovascular diseases in men older than 40 years. OBJECTIVE: To evaluate the association between erectile dysfunction and physical activity levels in a large cohort of men. METHODS: Data from 20,789 males aged 40 years and over who participated in the check-up screening between January of 2008 and December of 2018 were included in this study. In this sample, data about erectile dysfunction, physical activity levels, clinical profile and laboratory exams were obtained. Logistic regression models were performed. RESULTS: Individuals with erectile dysfunction were older (49.1 ±6.9 vs. 54.8±8.8 years old, p<0.001), had a higher body mass index (27.6 ±3.9 vs. 28.5 ± 4.3 kg/m2, p<0,001), and presented with a higher prevalence of physical inactivity (25 vs. 19%, p<0.001) than individuals without erectile dysfunction. The multivariate model revealed that age (p<0.001), hypertension (p = 0.001), diabetes mellitus (p<0.001), high body mass index (p<0.001), lower urinary tract symptoms and depressive symptoms (p<0.001) were independent risk factors for erectile dysfunction. Low or high physical activity levels (OR = 0.77; CI95%: 0.68-0.87, p<0.001 and OR = 0.85; CI95%: 0.72-0.99, p = 0.04 respectively) were protective factors against erectile dysfunction. CONCLUSION: Low and high physical activity levels were associated with more than 20% reduction in the risk of erectile dysfunction in men aged 40 years or older.
